When substituting the outdoor system, should the indoor unit also be replaced?

Our response is, it’s a good method. Here's why.

Matched design—Your furnace is made to function with a paired air conditioner. This might help better energy efficiency and performance.

Technology advancements—There have been many recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these perks year-round when you update the complete system.

Higher heating and cooling efficiency—Efficiency rankings are formed on matched unit performance. While getting one new unit will improve performance, efficiency will be lower from what it was envisioned to be. And your savings will not be as much as they’d be with a matched system.

Equipment age—If your AC is 10 years old (or older), your heater is likely just as old. Switching both means you’ll receive a lot of of years of efficient comfort, regardless of the season.

Up-to-date warranty—A new set of units also means you’ll receive updated equipment warranties. You’ll receive peace of mind knowing the warranty covers your complete system for the same time period.

On the surface, installing just a new AC or heating system might appear to be a good decision. But it’s not quite a good choice when you consider lower efficiency.

Installing an entirely new system could cost more, but you earn much better efficiency, reliability and comfort for years to come in San Antonio.
